Seriously, what did they expect ? 2 years of closure and using your savings up, world in recession, utility bills and gas up 80%, expensive flights, fear of Thailand yoyo'ing and getting stuck far from home, crazy high baht, some airlines still not flying direct to Thailand yet. The Thai government themselves caused more pain than the disease.
If Thailand seriously wanted more tourists they could start offering discounted rooms more, sub the national carrier to drop flight costs, try to get the baht weaker, loads more they could do, but they still think Thailand as some golden tourist hotspot that tourists will flock to - they are now finding out, people still wont come and those that come wont spend much , simply as they dont have much !
