...
(1) Did Oneweb buy LVs or launch contracts?.
(2) Was launch contracts with Arianespace or Russian operators of Soyzu?

(1)
nobody buys LVs - what would you do with it ?
:)
OneWeb signed contract for launch service.

(2)
The contract is between OneWeb and Arianespace.
Arianespace handles the launches from Kourou, while launches from Baikonur and Vostochny are handled by Starsem (Ariane's joint venture with RKK)

PVB?

Unfortunately I only get "Premature Ventricular Beat", "Parking Violations Bureau" and "PolyVinyl Butyral" as meanings for PVB :) Could you clarify?

The russian members can answer this better.
My guess: ПВБ - пожарная взрывобезопасность =  fire explosion safety / fire safety
A modification, not a stand-alone rocket

There is a missing step in the evolution. It goes something like: Soyuz-U -> Soyuz-PVB -> Soyuz-FG -> Soyuz-2.

The use of Soyuz-PVB designation is rare. Often just referred to as just another Soyuz-U. It is a 11А511У-ПВБ. 3rd Stage shared between PVB and FG.

Thanks for bringing it up, I didn't know about these variants. It looks like the video omits some minor steps, or englobes them into others, for the sake of clarity in favor of the current variants? I agree it would have been nice to include them into the tree, since they appear to be a handful at most. From this book: https://books.google.it/books?id=VNWxCwAAQBAJ&pg=PA23 I gather there are other 3 lesser known variants:

- Soyuz-U-PVB ("fire- and explosion-proof")
- Soyuz-U/50KS (with Ikar upper stage)
- Soyuz-U/RFB (with Fregat upper stage)

and perhaps:

- Six Molniya-M subdesignators for the upper stage (-L, -ML, -BL, -MBL, -2BL, -SO-L)

Energia has one contract in this period, №144/2953 dated 04.09.2017. I guess that as it is ПКК, it is a Soyuz-2.1a?

From Energia 2017 annual report:-
Quote
Договор на изготовление и поставку продукции (ракеты-носителя «Союз-2-1а» и сборочно-защитного блока) для запуска транспортного пилотируемого корабля «Союз МС».
Цена договора фиксированная 1 409 881 493,50 руб.
Сроки поставки определяются Ведомостью поставки (окончание поставки - – 05.2019)


Is this №Я15000-040?

Glonass-K is an assumption. That is probably, but only "System Glonass" is written there.

That's right. But which Glonass should it be for ?

One Glonass-M is still in stock at the manufacturer ISS Reshetnev (no.61). only theoretically

OneWeb plans to resume its launches from Russia
Quote
In May 2020, Dmitry Baranov, Director General at RKTs Progress, the manufacturer of the Soyuz rocket family, said that at the time, three Soyuz-2 vehicles configured for OneWeb missions were stored in Vostochny and one such booster was in Baikonur.

There’s a few places to find this, not certain what is the best website:-
Quote
Минобороны России заключило контракты на изготовление двух ракет-носителей «Союз-2» и разгонного блока «Фрегат». Со стороны Минобороны контракты подписал заместитель министра Алексей Криворучко. Контракт на изготовление «Фрегата» подписали гендиректор НПО им. С. А. Лавочкина Владимир Колмыков, контракт на «Союзы» - гендиректор Ракетно-космического центра «Прогресс» Дмитрий Баранов.
Контракт предусматривает изготовление ракет-носителей 14А14 (2.1а и 2.1б) и 14а15 (2.1в).
The russian military have ordered a couple more Soyuz-2 rockets, one with a Fregat upper stage.

MOSCOW, September 2. / TASS /. The second launch of the Gonets-M communication satellites, during which three vehicles will go into orbit, is tentatively planned in 2020 in mid-November. A source in the rocket and space industry told TASS about this.

"The preliminary launch is on November 16," said the agency's source.

Earlier, Nikolay Testoedov, General Director of Information Satellite Systems named after MF Reshetnev (ISS), told TASS that in 2020 the Russian Federation will launch not three, but six Gonets-M satellites. According to him, one launch is scheduled for September, another one for November.

The first launch of the Gonets-M communication satellites on the Soyuz-2.1b carrier rocket from the Plesetsk cosmodrome will take place on September 28 at 14:20 Moscow time. Three spacecraft will also be launched into orbit. Prior to that, the Gonets-M were launched on the Rokot conversion launch vehicle.

3 Gonets were launched through Rokot previously, so why don't they use Soyuz 2.1v for this launch now? Isn't Soyuz 2.1b a huge overkill as well as a much more expensive option for this mission?

I think the satellites ( 3x280 kg ) are too heavy for the Soyuz 2.1v.
So far the 2.1v always brought ~ 500 kg into orbit.
