Ok, if an article is 500 words long and the bot shortens it to 80 is still reasonable to call it TL:DR, however if there is a 1000+ word article we have two options:

Shorten it to 2-300 words and still give us most of the important details, or give us a two sentence summary, which is the true TL:DR for me, but most headlines also do the same job.

Personally option 1 is much better and I don't care how the bot is called. I'm okay with reading one phone screen worth of text instead of clicking the link and skimming through whatever side content and ads they have and reading 5-10 times as much.

Call it something else if you don't like the TL:DR bot name, or block it, but it's super useful IMO.
