Sure, I imagine the grandparent poster means arguing something like "limiting access for extensons is good because they're often used to steal financial assets". Old extensions are sold, or cracked and updated to inclue malware.

I want to avoid letting a meta-level conversation slip into object-level. But using the object-level as an example, I would expect a comment that acknowledges the types of things that are hard to build with Manifest V3, particularly more advanced adblocking, and acknowledges that there need to be solutions for those things, and makes the point that letting extensions be all-powerful does lead to problems and that also needs solving, would not get downvoted to oblivion. That's much more nuanced than, for instance, suggesting that Manifest V3 is an unalloyed good with zero problems, which I would expect to get downvoted.
