There are legit VPN companies. Mullvad would be my choice if I didn't already use Proton for their suite of software.
Nord is shit-tier. CCleaner is shit-tier. Raid shadow legends is shit tier.
Note which youtuber it is, and completely disregard anything they say.
I have never actually seen a Proton ad. I only looked into them after hearing about them often on privacy oriented subs.
