So far the only companies making you use one are the multiplayer gaming companies that are using TPMs for hardware IDs to ban cheaters and expensive corporate software using them for remote attestation on hardware the company owns.
If you’re salty about the whole Windows 10 thing, you’ve got until at least October 2027 until Microsoft drops support for it (security beyond the 10 year window announced at the launch of Windows 10 cost like 5 bucks a month though) or you can install an OS from someone who’s still willing to maintain support for old hardware, like Google’s ChromeOS or maybe Linux.
It’s only really a problem if you’re unwilling to pay for (or pirate) updates and are afraid to separate yourself from the large corporations building your current OS.
Capsacin is not soluble in water, so water and spicy food don’t really interact. Unless the water is contaminated, chugging water won’t do more than make you pee.
The capsacin applying signals as if your bowels are literally on fire and your body reacting to it as if it’s poisonous will, though. Many people can apply the same trick they can apply when they get the shits from milk: just consume a decent amount of it every day and your body will get used to it eventually. Not recommended if you have roommates or a difficult to reach toilet, though.
Of course it could be that standard Taiwanese drinking water is so contaminated that chugging it does give you mild food poisoning, but that doesn’t change the fact that people not eating large amounts of capsacin still get the shits when they eat spicy food.
