no it isnt, and yes they will.

and this is why we cant have nice things.

yes. there exists a tool called youtube-dl that anyone can download and do this for themselves. its not overly well known outside "i know how to use a console / command line" circles and this is a good thing. and it enables exactly this sort of "enterprise".

what this sort of low effort SaaS website really does is not democraticising such software for the masses. software that humanity needs. instead it will get projects like youtube-dl shutdown, all for a few ad clicks.

copyright exists. it is evil. but please stop trying to profit from tools that bypass copyright. let those tools live in the shadows so that we may all enjoy the fruits of their labour.

Websites like mine have been around for ages they probably will still be around for ages.

The only thing I am doing differently is to allow users to download their playlists/channels in a little more comfortable way.

And these tools are freely available on GitHub, don't think that would count as living in the shadows.

Yes, making private copies of material that you have legal access to for your own use is legal in many jurisdictions. In many places the content being "copy protected" affects the legality of copying, but I think youtube content it not?

Software like this has been around for years. YouTube does apparently change things in a breaking way every now and then and that's why tools like youtube-dl (and hopefully also this) receive continuous updates.

In most countries creating private copies of openly accessable material is perfectly legal, am not a lawyer and I cant talk for all countries here.

No it's not. (The whole "copyright" thing?)
