So far they haven't. Meanwhile, millions of people with older devices cannot use them to access wikipedia.

you're aware that your government is already doing this, right ? (your argument is invalid)

how? Edits on Wikipedia are public, including historical monthly backups available over bt all the way back to 2006, and I can ensure Wikipedia servers are serving it correctly by cross-referencing that and the edits. With http, any ISP (whose operators all tend to favor government cooperation) or switch in the middle could sed content to remove or slightly alter known-critical content.
