Sure, I use Proton VPN, but I'm under no illusions about flying under the radar if the security services adjust the radar.
For normal use a VPN just adds a nice layer of obfuscation e.g. bypass porn checks, but it also concentrates all the traffic very conveniently in 1 location for 3LA agencies.
Plenty enough for regular LE prevention given how they are required to have warrants to snoop on you versus lack of logging of decent VPN providers.
But ain't nothing stopping 3LAs if they want to see what's going on, it just depends on how big a target you are versus the resources they have available, they will simply get direct access to the hardware/use backdoors/brute force should they want to - but if you're naughty enough to be worried about this in the 1st place.....
They're not coming after regular uses like us thankfully, at least not yet...
And I think there are softer/easier targets if they want to clamp down on drug users.
I folllowed expert tutorials when setting up my Win 11 pc,
yeah I've done the same, it's a ball ache though.
I converted a laptop to linux a few months a go as an experiment, it's a bit flaky in places but I'm surprised at how viable it is as a daily drive for the basics, I won't be swapping back to Windows - added bonus that it works very well on older hardware, I picked up a cheap 5 year old ex-company thinkpad for £150 and it runs like a dream on it.
got to keep windows on my main computer though as use it for a few games I still play when I have chance.
