this is the serious problem, people. stop letting yourselves get conned.
if the source is not actually open on day 1, it's not free software and it's probably never going to become free software.
yeah, twitter, tumblr, etc all suck and have problems, but to break the cycle you have to use actual free software, not software that may become free software someday. until that software does actually become free (usually this never happens), you're either just a product or somebody they can lock into their platform and extort indefinitely.
