some of these tactics are so manipulative and they just spend all their time learning how to intentionally deceive others.
The First Amendment freedom of speech gives a lot of leeway to give various sales pitches. Anything short of outright fraud is unlikely to be prohibited, except as to minors. If you have a case of actual fraud you can sue, or actually seek prosecution by a prosecutor. If it falls short of fraud, you probably can do nothing. Matters of opinion (best, tastiest, easy payment plan, etc.) are unlikely to be found to be fraudulent.
If you only buy things that you yourself seek out, then these sales pitches are unlikely to harm you.
