What we need to do is convince all the disney adults in america that high speed rail would be a preferable way of getting to disneyworld compared to driving or flying. We could maybe harness their fondness for the monorail or something, but this is a group of people that has time, income, and passion that we could leverage. If we could direct 5% of the enthusiasm they have for limited edition popcorn buckets into calling their representatives and demanding high-speed interstate rail, we could get it by 2030
people are drawing Steamboat Willie Mickey doing all this crazy shit and whatnot, but you could always do that. you can do that now, with current Mickey, just fine. it's fanart and it's legally protected. hell you could take Disney-drawn Mickey and put a caption about unions or whatever on it and it would still be protected under free speech and sometimes even parody law.
what is special about public domain is that you can SELL him. you could take a screenshot and sell it on a tshirt. you can use him to advertise your plumbing business. people have already uploaded and monetized the original film.
you could always have Mickey say what you want, but now you can profit off it.
