As others mentioned, you can't stop them from doing this. It's a cutthroat game where companies will try to poach customers however they can.
Best defense is making your customers so happy they won't switch, but tactically:
- Create a private Slack/Discord for paying customers only (harder for them to infiltrate)
- Move community to a platform with anonymous usernames (Something similar to Reddit-style forums or Discord with display names)
- Add some soft vendor lock-in -- a bit evil but sometimes necessary - just maintain the balance between retention and not being user-hostile
On a positive side, if a VC funded startup is this desperate to poach your users, you're clearly doing something right.
IDM - Internet Download Manager -- Only available for Windows, never saw a proper alternative for Linux/MacOS with the same reliability and browser integration.
Though no longer download videos/files enough to complain about it.
I end up using yt-dlp on macOS/Linux to download videos if needed. It’s worked on pretty much everything I’ve tried it on so far. Though admittedly not at seamless as a button being injected into the page itself.
Does youtube-dl still work? There seems to be a cat and mouse game with these things. I won't update it for a while and it will break, but it always works again after I update. I figured without active maintenance youtube-dl would be pretty useless by now.
But let's be real - nobody actually does that.
