As a person who always eats the whole apple, stem and all (have done so for years), I'll object to your "apple seeds do not taste good" statement - tastes differ, to me they are delicious, certainly on par with other "normally edible" seeds like sunflower seeds! Of course I wouldn't eat them in any great quantity because of the poison issue.
By "they don't taste good" I wasn't trying to imply that they taste bad, though maybe they do to some folks. At least to me they don't taste like anything (they lack a good flavor). For me and probably many folks, the flavor isn't something that attracts me to eating the seeds.
I also eat the whole apple and like to crunch the seeds.

Bloody 'eck. This sounds like a chat around the back of the bike sheds off of the '70's onwards.
Yes, apple pips do have a tiny amount of cyanide in them (but why)
This is a from a reasonable source and relates to cherries: https://www.bbc.co.uk/news/uk-england-lancashire-40738573
I think we can assume that apples and cherries are OK to eat. Apple pips are fine and why on earth would you want to crunch through a cherry stone.
