Switching to Firefox is really not needed at all to evade this one. Just switch to a different Chromium browser than Chrome itself, then use your browser's own extension store.
I use Edge, my adblocker is in Edge's extension store. If Google is throttling updates to my adblocker to help in their fight on adblockers, I can just install the one from the Edge Addons store and that problem is solved. I'm sure other Chromium browsers have their own extension store too.
Why do you expect that Edge wouldn't adopt Google-like MV3 along with Chrome?
Microsoft adopted Chromium in order to minimise development costs in a product it doesn't see as core, something which would be incurred if it had to maintain its own fork of mv3, and is incentivized through Bing to pursue a similar approach.
??? I didn't suggest it would, that's an entirely different topic.
Do I need to read the article, is it actually about something completely different than the headline says? Because that's what I was talking about, the headline, since I've seen that argument before.
When in a discussion about an article, it's usually a good idea to read the article since it may make or address the points that you want to discuss. The headline (in this case) is just the conclusion and you're missing all the supporting evidence that leads there. Taking just headlines and assuming the context leads to being misinformed and spreading misinformation.
my adblocker is in Edge’s extension store. If Google is throttling updates to my adblocker
For instance, you are assuming that this is related to Google maliciously throttling extension updates which is not true.
YouTube is pushing new ad-block circumvention approximately daily.
Microsoft's documentation states that extension updates can take up to 7 days to pass certification and go live.
That is not materially different than Google's behaviour in this context.
