Debian has a package called popcon (Popularity Contest) which tracks package usage.

You can search a package name. I made an example graph showing web browser usage. This may not be fully accurate because it isn’t showing proprietary browser such as Chrome or Brave.

redact dot dev is owned by a guy named Dan Saltman. Dan Saltman is the cohost to liberal youtuber Destiny (Steven Bonnell). Dan Saltman is openly Zionist and has tried to have all anti-Zionists banned from streaming websites, such as twitch. I would avoid using redactdev. I don’t trust them to securely delete things.
