A lot of members here have said fast chargers damages your phones battery long term. Is that really true? Why doesn't Apple include a fast charger with their 1k+ phones when the majority of Android makers include it in their phones?

Battery university has lots of good information on li-ion tech and I would look to them before a click bait youtuber.

Dude you wont probably use your phone for more than 5 years. Don't worry about changing & battery and all.
Use any charger as long as they are good quality (from big brands) & you are good to go.

Why would all the other majors offer a fast charger if it damages the battery, except Apple? WTF man?

Apple not throwing a fast charger in the box is not the same as the phones not supporting higher wattage charging.
If you want to ding apple for the 5 watt charger it’s legit but not unexpected.
Why does that necessarily mean anything or even relate to one way or another as far as fast charging being harmful in some way?

It was a sort of myth perpetuated by Apple people to excuse the lack of fast charging for years.
The truth is millions of people have owned phones (basically anything that isn't an iPhone) with fast charging and nobody has ever had any problems.

If you want to get technical, fast charging theoretically can cause a battery to experience more wear over the years. In a practical sense, I would expect that the effect would be negligible over the time period that most people keep a phone/battery.
I guarantee this is not why Apple doesn't bundle a fast charger.

Technically, yes, battery wear out faster when being charged with a fast charger.
But how much might not be even significant for you. As already said, that is not an excuse for Apple not to include fast charger.

I completely agree. It's even in their specs as a feature sold separately:
Fast-charge capable:
Up to 50% charge in 30 minutes
with 18W adapter or higher (available separately)

Heat is higher when using a fast charger. More wattage = more heat. And heat is the number one enemy of any battery.
The thing is, probably most phones have sensors to detect when there is more heat than expected, so it would automatically lower the current to prevent serious damage.
It will still be harmful to the battery but probably not enough to notice immediately, maybe after one year or more.
Remember, fast charge was not introduced to be used all the time, but when you need it!
Some phones (like galaxys) let you disable it and charge at normal pace.
