They are not obligated to answer correctly every question foreigners ask. Thailand is allowing foreigners to live a decent life in the country that one cannot get in his home country. What more do you want? It is not a privilege.
Any company professing their workers can work remotely from anywhere in the world is committing fraud and aiding in the tax evasion. If a worker is working remotely in another country, the company is responsible for paying his taxes in the host country. For twenty years I have worked remotely in some of the world's top companies like Google, Facebook, Microsoft, Oracle, Qualcomm, and AMD,, and all have clauses that I can only work remotely in US territories only.
