Wouldn't that require physical access to our WiFi devices?

Sidenote: My ProtonMail account was completely compromised... I had sent a professor an email based question, pertaining to his research that implicated MKUltra being directly related to sexual acts committed by high ranking Political/Military officials as a blackmail technique. It was one of 2 emails I had sent from the account.

I was able to access it daily, every day, since I created the account to send the email.

Today, I am totally unable to gain entry into ProtonMail and my account has been blocked. If I reset my PW, Proton informed me that it will delete all sent/received mail.

I have a sinking suspicion that the Professor is under watch and his response caused my Proton account to be actively compromised. But, of course, no way to actually prove it unless Proton hands over server logs...

Or I was hit w/ Cherry Blossom and they've actually been in my residence. I'd prefer to believe the former.
