This strikes me as almost conspiratorial thinking, and it's reflected in the article. At one point they say KOSA is unpopular but.. it isn't? These laws (KOSA, OSA) enjoy broad, bipartisan popularity and politicians are jumping on the bandwagon because they want votes. It really is as simple as that.

There's absolutely no way to counter this, or at least to round off the censorship power-grab this is allowing, if we don't admit to ourselves that people have become suspicious of the tech sector (us) and are reaching to clip our wings - starting with access to their kids.

The laws are only moderately popular in the abstract, but when you show people the reality and the future implications then popularity drops. The key is educating people about the dangers of this type of legislation, including dangers to privacy and authoritarian control over information. In the US especially both major parties hate each other with a passion; this animosity can be leveraged with proper framing.

What do you mean it's not unpopular? How many voters have ever expressed interest in this?

If the politicians keep voting for things their constituents don't (and in these cases actively push back against so hard that the politician are forced to withdraw the push) that seems like strong evidence that politicians are doing something with an external incentive...

Politicians having bad incentives (e.g. campaign donations) isn't conspiracy thinking, it's a documented reality. Hell, we even had a supreme court judge taking a present from somebody who's case he was ACTIVELY OVERSEEING.
