As if it's not bad enough that videos automatically start playing whenever you move your mouse over a game's thumbnail image, I noticed today that the videos frequently do not play. Instead, they show the message "This video requires payment to watch". The GOG main page and the store/sale pages are showing this message for most games. If it doesn't show this for a particular game, then moving the mouse off of the thumbnail and then back on usually results in this message being displayed. I'm seeing this on different versions of Firefox on different computers, so it doesn't appear to be a browser or computer issue. Personally, I think it's funny since auto-play videos are one of the worst things GOG did with the site redesign.

You must be doing something impressively wrong to end up with a message like that; sounds like you're landing on Youtube Red (their premium content schlock) rather than the intended GOG.com videos, which load in about a second.
