Personally can't wait until thundermail has a free tier
You could check redlib and put the links in it

Here's some of protons response
a browser written entirely in rust, should be fun on redoxos when it matures (all rust operating system with a mini kernel)
if it makes you feel better i know an employee there and theyre a communist and say a lot of mullvad employees are lefties too, idk if they have a union or anything. nym vpn has chelsea manning backing it. not really a traditional vpn though its basically unfree tor that is not slow as balls, has the benefit of really good server coverage and few people blocking it. coolest thing is you can use a seedbox to route traffic to pay it down.
i actually work in software security.
grapheneos has talked about integrating shields into vanadium (and by extension, trivalent) which i would love. shields imo is a very top notch implementation of an ad blocker and is better than ublock origin in every way due to how it blocks in ram with rust rather than in userspace like ublock. brave does pretty well at integrating many things into the browser so that the user isnt tempted to install extensions, which reduces attack surface. i consider email aliases, automatic darkmode (can be enabled via chrome flags) on sites, and a built in adblocker (not an extension, it must also work on videos) to be critical for user experience, and ideally via no extensions. currently only brave offers each of these stock, which is very unfortunate. plus it has better sandboxing, there are many exploits to harvest fingerprints on many corporate sites that circumvent sandboxing in firefox and read other tab data. basically, the only options are brave with minimal changes, mullvad browser with no changes, or tor browser with no changes, and you should not open more than one tab on any firefox browser. the last two are not great for usability every day due to no automatic darkmode, among other features.
i think the best way for brave to improve would be maybe to include something like sponsorblock in the browser as well and then work hard to cut off providing extensions altogether, as extensions are a main source of fingerprints becoming unique and data leaks. and of course remove all the crypto garbage.
jet engines? what the fuck
crypto is useful too, without monero i wouldnt have hrt. place i live in is a shithole and doctors are highly restrictive and far too expensive
but monero is the best one in terms of privacy and it is unprofitable to mine it unless you have the latest and greatest green processor

It's better to silo things that require you to install an extension on browsers into a different app. Extensions alter browser fingerprints. So this let's you sponsorblock and AdBlock YouTube without worrying about fingerprints on all other sites
Also has a nice way to handle subscriptions without login
