adblocking "users" are not Youtube's users. What do you mean blocking ads has no bearing on their service? It sounds like you are saying user experience is "I should get this for free".

YouTube itself is offered for free. The creators of content are not Google employees. Adblocking is a safety measure on my own physical machine. Not YouTube's users? Maybe. But I am, so by that metric there's some doubt. I paid for over 2 years for the premium, the cost increases and it's cheaper to pihole everything and support the usual suspects on patreon. It's become a scenario of "I've given you so many adverts,…

Making a profit doesn't mean that their costs aren't so high that adblocking isn't compatible. Walmart has profits of $157B in 2024, but their business model isn't compatible with people just walking in and grabbing stuff without paying - and doesn't make it ethical to do so even if "they'll be just fine even if I do that"

The biggest difference is still the difference between physical stuff that only exist once and information, that just needs to be copied without loosing any value.

> a huge staff and they're still losing. that's because these staff are just there for a pay cheque. The yt-dlp maintainers are passionate. You will find that the passion wins.

What environment are you using that: - Has access to Youtube - Can run Python code - Can’t run JS code If the concern is security, it sounds like the team went to great lengths to ensure the JS was sandboxed (as long as you’re using Deno). If you’re using some sort of weird OS or architecture that Deno/Node doesn’t support, you might consider QuickJS, which is written in pure C and should work on anything. (Although…
