The actual reskin is technically not all that challenging, for all that I'd still not want to do it just for fun. I'm sure that if Mullvad wanted to, they could have released a rebranded Tor Browser with their own development team. But that would have meant missing out on what is probably the main point of the exercise, which is giving more¹ money to the Tor project to make things better for everyone.
[1]: See also https://www.torproject.org/about/membership/, wherein we discover that Mullvad gives Tor a minimum of $100k/year for membership.
Options for incrementally improving privacy are still good, even if it doesn't go as far as the normal Tor browser.
This whole thing STINKS.
I think Tor is inferior to be honest.
If someone uses a commercial VPN I think they're privacy conscious. If someone uses Tor I subconsciously assume something else.
I wouldn't be recommending Tor to my friends of family.
Huh? The Tor Project is primarily funded by the US Government.
