Yes I agree Surfshark has done some weird things. I find it weird that it's actually the same company now as NordVPN, but they don't make it clear.

Regarding performance, Surfshark is decent speed but still slower than not using a VPN. The more annoying thing is that I get a lot more captchas when using Surfshark. I think these issues are common for all VPNs, though I haven't tried Mullvad yet (I will when my Surfshark subscription ends).
