Lol the biggest reason you're wrong to make that comparison is that Hong Kong was never its won country. Hong Kong was a British colony and then a Chinese special administrative region (SAR) given a degree of administrative autonomy by the Chinese government voluntarily as part of a treaty with the British. The treaty expired and then China decided to change the rules for Hong Kong.

Taiwan meanwhile was the territory that the Republic of China (RoC aka Nationalist China) held on to when it lost the Chinese Civil War against the People's Republic of China (PRC aka Communist China) who now control the mainland. The PRC never controlled Taiwan and the RoC government which rules there does not answer to the PRC nor has it ever. The PRC and its Communist Party can claim that Taiwan is a rogue province all they want but that's a lie. Taiwan is not theirs it was and still is under the government of the ROC even if the ROC has lost the rest of its territory to the PRC since the Civil War and World War 2.

Hong Kong's city government allowed China to take more direct control because it always answered to China since the British gave it to China. Meanwhile the ROC government in Taiwan has never answered to the PRC and it never will. Opposing the PRC is literally one of the main goals of that government and country and I don't think there are any major politicians there who want to join the PRC willingly nor would amy such politician be popular there.

Long story short the ROC (Taiwan) and Hong Kong are not even remotely comparable and the former won't just accept any attempted takeover by the communists.
