I have to disagree that I'm perpetuating any falsehood here. Mozilla literally needs to approve an addon for it to behave normally. That you are satisfied with the process they have for approving doesn't change that.
To me it seems absurd for a company that claims to be so pro-privacy to not allow any genuinely private extensions to exist. Anyone who wants to make a 'real' addon has to share their code with mozilla.
I actually mostly had the top poster in mind, not you, sorry for the confusion.
What you're saying is technically true, but also not relevant, as explained. They can have the best system in place today, and just change Firefox tomorrow. So it doesn't really matter how the system works now. This is true for anything from Mozilla to XFree86 to Redis to left-pad.
De-facto reality is that right now anyone can create an account and just create a signing key and distribute their extensions $anywhere. Approval is little more than rubber stamp. Mozilla not going around granting "approval" or anything like that.
And they certainly didn't revoke the very weak "approval" here; people can distribute and install it. It's just not listed on the Russian add-on store. So that makes it doubly irrelevant.
