A member of my Thai family recently made a Facebook post mocking the blatant deception of a packaged food product, cheafly the fact that the packaging was unreasonably 5 times bigger than the contents to make the consumer think they were getting way more than they were actually getting.
Someone shared that post to the page of the company that produced said product. The result was they got a visit from the police and threatened with court action if they did not remove the post from Facebook.
This is not the first time I have come across this in Thailand. Look at the Andy Hall case where he was being sued for $10 million for breaching anti-defamation laws against a pinapple canning company or recently a farang who complained that his covid hotel experience was terrible and ended up being arrested.
In Thailand the truth doesn't matter, the justice system will ALWAYS find in favour of a big company against a mere peasant when it comes to defamation laws.
This is a stark reminder that the legal system here contains zero consumer protection rights, it is there to protect the big guy from the little guy rather than to protect consumers.
