The impact is the same as when mail started to block spam. There will be a initial decrease and complain, followed by change to more professional behavior in the industry.

For example, mail news letter used to be sent out in mass to any email that the company has harvested. That tactic is now illegal, so they only send out to customers who has subscribed to it and the letter must have instructions on how to unsubscripted.

However, your friend do not actually support people if they don't also click on the ads and buy the products. Money don't get magically created, and people need to buy products before any content creator can get get compensated for supplying advertisement.

Reputable people may do that but my mail server is still getting 1000s of spams a day.

Correct, and this is the business concept behind technology that is intended to block spam while still permitting the reputable mail passage to the user. One of the commonly argued reason to use gmail has been its spam blocking features.
