Not affect anyone, it will affect search engines... but, not much nore than that.
And the protests proved inaffective, as I initially thought and said to many, just move, no need to protest, just leave for Lemmy and leave your accounts. That was all that was needed and no protest in the world is gonna beat reddit or the admins that will just overried your NSFW settings. Leaving the platform says way more than protesting this or that.
And no, if the point of the protest was to just delete all info from reddit, then I would've never been behind that protest. The delete everything idea was promoted by some extreme protesters and unfortunatelly, some users went allong with that.
I usually use 7z as well... mostly because of the higher compression ratio. I resend in zip if I get complaints, but if it's a large file that barely fits in size on whatever hosting service I decide to share the file on, I just tell them to install 7zip or any other archiver that can open 7z archives. If they don't how to do it, hey I also offer remote IT assistance ๐คท.
