I believe these blames are personal dissatisfaction.
As a Thai, I can think of many other reasons to blame Thailand’s free TVs.
1. Nowadays, private free-to-air channels have become fully commercialized. They are saturated with "direct sales" segments—advertisements for products—sometimes inserted into the middle of the actual programs people are really watching.
2. Some channels present superstitious or non-religious beliefs, even presenting such content as "news," which I find entirely inappropriate.
3. Certain Thai TV channels lean too far into "woke" ideology, airing gay/lesbian dramas.
I believe such content should be limited to specialized platforms or paid platforms rather than being broadcast publicly—where the inappropriate films are easily accessible to children, or where the inappropriate scenes might be seen/watched by children in public spaces, shops, restaurants, etc.
The advertising of those kinds of dramas should not be visible in public places too.
The homo-style advertising are inappropriate in public places. Those ads can also be very disturbing to see.
Previously, I see a news about a young Thai actor had all his contracts with a Thai entertainment company (who also owns Thai free TV channels) terminated simply because his social media account having views that were "not woke" and/or pro-heterosexual and probably showed support for Trump. In my view, he does not deserve termination or any punishment at all. This is an injustice he has had to face. He has rights to share what he think (The First Amendment). People has the rights to "not woke" or being conservatives. The far-liberal entertainment sucks for removed a conservative actor like him.
4. There are various other issues, such as the use of loopholes or tactics that allow for the advertising of alcoholic beverage brands (except in the foreign sport games), the allowances of Chinese automakers as sponsors for certain TV programs, or the live broadcasting of Pride events or gay parades.
