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!
