This discussion about bricking the phone after a locking attempt is interesting, also mentioned on the Divest wiki : https://forum.fairphone.com/t/trapped-in-fastboot-mode-with-locked-bootloader-and-corrupted-custom-rom/80985/280
I just used fastboot to get the locking ability, the result was 1 so it could be locked, I did and it went ok. No problem since.
That's what some people said online but yes there is ideed arb on it, there are some technical details on the /e/OS FP4 page for instance : https://doc.e.foundation/devices/FP4/install.
I was using Calyx and went to Divest with relative ease, atlhough I did pay attention to the security patch level before jumping, having to send the phone to fairphone would be really annoying.
Just be careful if you test several android roms, the phone uses anti rollback (ARB), like pixel phones. In certain circumstances it's possible to brick the phone, and you'll have to send it to fairphone.
With android roms that allow relocking the fairphone bootloader (Calyx and Divest for instance), really check if the bootloader can be relocked via fastboot command-line, it will brick if it's not the case.
I spent some time reading before attempting anything on it and it went rather smoothly, I don't hop a lot between roms though.
Kinda defeats the purpose (for me at least). I didn't use revanced but if I recall correctly, to subscribe to channels, you have to use a Google account. I closed all my Google accounts a few years ago, so having apps like Libretube and Newpipe is nice to keep track of new videos from channels I like.
Also it's still the YouTube app so it comes with their algorithm and the trending stuff I really hate...Unless we can hide it now? With original Vanced we couldn't I think.
It's not a total ban of VPNs, I went to read a bit on the subject (easier since I'm french), it's just that some politicians came up with a few amendments relative to the bill called "SREN" which very literally translates to "Securing and regulating the digital space". As you may guess that bill also ticks the "child porn" box as a reason why it came to existence.
One amendment proposes to ban mobile VPNs that do no comply with European or french regulations in the context of app stores. So it's only on mobile, nothing about desktops.
Of course it's inapplicable in practice.
Several amendements already failed due to backlash, one was about preventing people from posting on social networks if they use a VPN.
