Here's the repo if anyone is interested. I still use it to this day but haven't worked on it in a while cuz I'm learning rust.
I suspect that's where instagram is aiming, and they probably see a point nearing where that'll be forced on them by european government(s) attempting to reduce the amount of high profile 'social media' suicide.
An optional opt-in system like your implementation is great, but sadly doesn't tackle that problem.
Social media is both seen as contributory to rising suicide rates among youth, and integrated into suicide attempts (eg live broadcast)
On sites like this one, I don't cast a lot of votes up or down with one exception. If I post a comment, I upvote every single reply for two reasons. One, I'm happy that somebody chose to reply and two, it helps me keep track of new replies. It might be a misuse of the voting system here, but as far as I can see, there isn't a better way of spotting replies.
There’s an adblock filter for comments[1] which works pretty well. This is thematically similar.
I'm definitely not installing an extension just for this.
I also think the security will be better on my extension. You have to give greasemonkey edit permissions for all websites whereas I have a PR in the works where you only grant permission to the sites you want to disengage from. Even now it only asks for permissions to the subset of sites it modifies. Due to the nature of how web extension manifest permissioning works, greasemonkey can't offer this. If you look at their permission model it says "This add-on can: Access your data for all websites". IMO that's way more dangerous than your paranoia about a new extension with tight permissions.
