I switched to hetzner hosted 'own domain' a few weeks ago, which includes webmail (I use thunderbird client). YouTube failed to delete, even though I'd deleted all content a couple years back, but deleting the complete google account worked! (and feels great!) Funny thing was that I was then blocked from sending email to other gmail accounts. Turns out there are a couple simple switches in the hetzner web interface to enable some of the anti-spam measures these big tech receivers require.
