Something that TSR did not promote during the 80s and 90s was the hobbiest/sharing culture that got the whole ball rolling in the 70s. In many ways it paralled Bill Gates and the software industry.
Playing the part of Stallman was Peter Adkinson, who started WotC. When WotC acquired TSR in the 00s, it was a boon to the RPG industry as the OGL was formed to foster the hobbiest community and other companies to share and collaborate, but Hasbro went back to the older ways with 4th edition and put it under a restrictive license.
Looks like the OGL is back though as WotC has released an SRD for the 5th edition of Dungeons and Dragons.
The hobbiest community is still strong. Some things are created under other open licenses. Every year since 2009, the One Page Dungeon Contest (https://onepagedungeon.info/) holds a competition with all of the dungeons put under the Creative Commons License for people to share, remix, and build off of.
