A plethora or suspicious things? If the companies are breaking the law, the FTC can sue them and win. If the companies are complying with the law, the FTC should indeed do nothing. If the law is bad, congress can pass new laws.
What's not OK is for the executive branch to not like the law, but be unsuccessful at passing new law through the democratic process, and then use the FTC to unsuccessfully sue companies in order to punish them (and threaten others) with costly legal expenses.
It's not that simple, because people don't know if they're breaking the law. The job of the FTC is to clear that up. It's a fallacy that laws can just be followed or not, almost all the time it's in a gray area.
I’m specifically talking about the situation where you lose almost all the cases. When that happens, it’s not called “clearing up the law”, it’s called frivolous lawsuits.
