Mainly, IMHO, sensationalist "journalism" like this is much more of a reason why we can't have nice things, compared to the actual event predicted (which likely isn't going to happen, at least not to the extent described).
Do you honestly think that using Gmail protects me from the NSA? If the NSA wants into my computer, it's in.
Secret services swap their data, so they can all read my santa letters.
There is the viewpoint that one should prefer one's own jurisdiction regarding storing data (I know you don't like Schneier but he e.g. holds that viewpoint).
I use an email provider from my country. If a judge from my country wants to persecute me, they have to complete a legal request which is tested by my provider.
If I used an email provider from Switzerland or the US, is that also the case?
Also, it's important to think of the economical aspect. If i financially support providers in my home country that lobby for better privacy laws and don't engage in surveillance capitalism like Google does, isn't that creating a good alternative that can also be properly regulated?
Plus, it's one dependency less from a (more than) half MAGA country.
So your recommendation makes sense if you are a citizen of the USA, but not everyone here is.
Addendum: what do you actually mean by "security"? For me, that is also "being able to access my email account whenever I want" and that this account doesn't get closed, even if I do shit on the internet, whoever that decides. Google shouldn't have the right to say "these actions are uncool so let's kick this guy" (never happened to me, but I don't even have a contract with Google!, they have the right to cancel my account whenever they want.).
