Comments
At a glance, I'd remove:
Telegram - use these instead: https://www.privacytools.io/software/real-time-communication/
Ubuntu - why? On recent updates Canonical added Amazon ads to Ubuntu.
ExpressVPN & PIA - why? There are better alternatives. See: https://thatoneprivacysite.net/
Wire - JUST got removed on Privacy Tools this month. Got bought by a US company. News was on the front-page of AlternativeTo.
Brave - Has built-in ads, collects your data is Chromium based. Use
Mozilla Firefox or 
Tor Browser or 
Falkon
Infinity Seach - Personally I use
DuckDuckGo but we'll see what infinity has to offer on the long run...
Your list is important but it's bloated and full of doubtful suggestions. This can be misleading to uninformed users. Please revise your content! I'm happy to help with the little I know.
[Edited by coralinecastell, January 10 TO REFLECT RESPONSE BELLOW]
This list will be updated shortly as we were unaware of some of these recent events. We started out this list by gathering many products that are generally known for valuing user privacy but there are several more alternatives that we will add to this and we will remove some as well. We are also migrating many of these products to a new list that is just going to be Google alternatives that do not pass for being completely privacy based.
As for Infinity Search and the other search engines included here, they will remain on the list because they are still privacy products. DuckDuckGo has always been included in this list but it is not the only reliable privacy based search engine. Others include Infinity Search, Qwant, Searx, Mojeek, and several others which can be found at .
We appreciate your response and please let us know your thoughts on our new revisions!
