If your Gmail account is lost or compromised, good luck getting any help from Google; while G Suite support is decent, free Gmail account users are basically on their own.

In the Etherium case, he deleted the email and wanted to get it back 2 full years later. The only way he would have recovered from this would have been to take meticulous backups (and test them regularly). I would expect any 3rd party provider to honor my wish to delete data, especially 2 years down the line (and, in fact, they are probably legally required to do so).
In the "lost in the Google void" situation, the user set up 2fa but lost all access to their 2nd factors. I don't see any reasonable recourse to this, as any "solution" Google implements would undermine the entire purpose of 2fa.
The remaining two are obvious issues with Google's service. The "gender pronoun" one is a bit odd because gender pronouns don't seem to have anything to do with the account closure (there's speculation that he was mass-reported to exploit their abuse response systems).
Not sure if it's simple but how do you intend to protect against DNS record hacks?
