I get that advertising is effective by scale. You're more likely to choose something you've heard of. But I still can't help but feeling resentful for a company when they're out to steal my time and attention.
Is all unsolicited incoming communication such "stealing"?
At the very least the transaction is unfair since the spam part is generally left very implicit.
Unfortunately companies I do business with are allowed to try to sell me things. But the Outlook spam filter is pretty good.
