Nice guide that was posted on that other site.
I know you did not make this guide, but here are some corrections and more stuff:
Browsers:
- LibreWolf is a good private browser.
Search Engines:
- There should be markers for Bing and Google index-based search engines.
- Mojeek is a sustainable, private, non-US search engine, that has its own search index.
E-mail:
- Proton Mail has a scandal involving one of the founders saying pro-Trump things through their official Twitter account.
- Tuta and Proton Mail have very good free tiers, you likely won't need to pay at all.
Social Media:
- It is Mastodon, not Mastadon.
- Akkoma is better than Mastodon, it has 10 times the character limit, and pledges to be sustainable, AFAIK. It's fully interoperable with Mastodon and the rest of the Fediverse, too.
- Threads is also a microblogging platform that should be replaced.
Edit: The browser stuff is covered in another part of the guide. My bad!
