If I understand it right,

• the time-lock is from the time the recipient (Carol) starts decrypting the encrypted file sent by Bob.
• future microchips, according to Moore’s Law, will decrypt the file much faster.

Please correct me if I’m wrong.

SimpleX has the best privacy, because of removing metadata.

Signal comes close, and has many more users. Probably some of your friends already use it.

If you want something similar to Telegram/Discord/Slack, then Element (Matrix) is what you’re looking for.

All of the above are E2EE.

NewPipe SponsorBlock

Apps that don’t work:

• Google Pay

As far that I know, that’s it.

There’s NewPipe, which is open-source.

Why not Element/Matrix?

Try https://simplex.chat. Better privacy and no phone number required.

Most cryptocurrency communities use Discord or Telegram. It’s such an embarrasment.

You can just continue using Signal. All the alternatives will disappear from the app stores too unless they spy on you.

A recent alternative with even better privacy is SimpleX: https://simplex.chat/

Elon didn’t say he would charge all the X/Twitter users. The media just made that up.

Good for Mastodon, though.
