For what it's worth after I gave them my email, either they didn't send me anything, or they did but they honored my unsubscribe request, and I can read all the articles.
A few years ago I switched the mail provider for the company I work for from a small MSP provider over to Google Workspace. The reason is my boss' inbox had an average of 5k+ of spam daily. He even had to abandon one of his email addresses at one point. After switching over to Google that number went to a more manageable few dozen daily.
It's absolutely a massive problem.
