ChangeTip failed, along with all other microtransaction applications because tx fee went from .0000 US cents to about 20 US cents.
That's not why they failed. Their business model was horribly unsustainable. It's currently 15 cents for TX median size. You can easily go lower though.
Many, many other application that are not settlement application also failed as a result of Maxwell/core/blockstream intentionally corrupting the system to drive demand for their LN which doesn't even exist today.
Repeating the lie infinite number of times won't make it true for non-sheep users. You still are unable to list anything that would come close to a list of 'many' (not to mentioned 'many many').
