It might be as annoying, but I don’t find it quite as evil. At least that is just Google deciding to put an ad on their own website that is annoying… it isn’t abusing the browser to put an ad on someone else’s website

That's just ads. You are also welcome to pay for using Gmail or any other email provider.

And fortunately, it didn't add these ads to your outgoing email, like Microsoft used to do.

You get free email they get to advertise to you. Understand?
