EDIT: Apologies. Updated with a link to what gorhill REALLY said:
Manifest v2 uBO will not be automatically replaced by Manifest v3 uBOL[ight]. uBOL is too different from uBO for it to silently replace uBO – you will have to explicitly make a choice as to which extension should replace uBO according to your own prerogatives.
Ultimately whether uBOL is an acceptable alternative to uBO is up to you, it’s not a choice that will be made for you.
Will development of uBO continue? Yes, there are other browsers which are not deprecating Manifest v2, e.g. Firefox.
They lost what may end up being the biggest antitrust case in decades. And it’s not weak sauce like the ruling that may get overturned regarding the Play Store monopoly (which is kinda weak since Android manufacturers can and do include other app stores on their phones).
It had to do with their anti-competitive behavior regarding Online Search. Specifically stuff like paying Apple and other manufacturers to make Google the default or even exclusive search engine, then using that not only to capture the market, but to charge more for ads than the competition they sabotage.
As a bonus, it’ll probably hurt reddit too, since it almost certainly makes their recent deal with Google illegal.
It’ll be appealed, but it’s a pretty big ruling. Between the US Courts, EU legislature, and what looks poised to be a flop for Gemini/Bard, Google is on its way to having a real shit year.
I find I can bear their discomfort with extreme fortitude.
