I wouldn't call it being entitled to the fruits of other's labor for free. Youtube content creators get paid through ads and sponsors. The platform's payment system is already in place, it's not pay-per-view. If the video doesn't have what I want, then there are plenty of other videos that DO have it, for the same trade-off, which is viewing ads or buying things through their links. A guitar channel recently said they sold 18 million dollars of product with Sweetwater links.Personally, I have no problem paying for the work someone else has put in to create a tab.
It’s brilliant how much free stuff there is available online, but when did we start thinking we were somehow entitled to the fruits of other people’s labour free of charge? That’s one of the things that’s so good about Patreon IMO, you can contribute a few quid a month and get access to some amazing content. I say, go for it, Smitty!
I could also ask, why would a creator go on Youtube which is a free ad-supported platform, and then expect people to pay extra for tabs that they're withholding through Patreon? They're allowed to do that, just as anybody should be allowed to not view their channel when there are so many others available. A lot of the channels I sub to, do have their own paid lesson packages, but they also provide useful content in their Youtube videos without paying extra. I understand supporting a Patreon if it's a creator you really support and consistently get content from, but to get the tab for 1 song, definitely not for me. I will gladly pay for a tab book (and have done so many times) provided it has enough songs that I want to learn.
