Probably. Unless they’re only using that as a hook where there are still other forces not directly involved in the creative/hosting process that are taking 90% of the profits.
EDIT: just realized you’re probably talking about stuff like patreon where you actually just pay the creators, in which case, absolutely! I’ve got a number of patreons I’m actively supporting
Are you talking about the planks the track’s laid on? Pretty normal for that to be wood actually. The AMTRACK tracks in the USA DC area are all like that.
