Tired of seeing software that he and others had written appropriated (without acknowledgment or compensation) by disreputable software companies and then told to pay for software they had written, Stallman took action, creating the foundation
The anonymous contributor needs to get a better grip on reality.
The software in question was mostly written by programmers who were MIT staff members and students. MIT held the copyright on the software that they developed. MIT subsequently licensed the software to at least three companies: Symbolics, LMI and Texas Instruments. (I don't recall if there were any others.)
The founders of Symbolics and LMI included many of the same people who had worked on the software as MIT staff. Stallman remained an MIT employee.
Nothing in this story makes Symbolics or LMI or Texas Instruments a "disreputable software company". MIT has a long history of licensing technology developed within its walls to industry, often to startups formed by ex-MIT employees. This was no different. (At least, at the time this was no different. I have no idea what MIT's current practice is for software developed by its employees.)
Stallman's unhappiness with the fate of the software he had worked on motivated him to invent the GPL. This was indeed a wonderful idea that has done an enormous amount of good for the world. He deserves a great deal of credit for this.
But there is no need to over dramatize the birth of the GPL by painting the companies who licensed the Lisp Machine software as some kind of evil villains. They weren't doing anything different from what many other computer companies of the day were doing.
And (as many others have noted) Stallman was never the director of the MIT AI Lab.
Indeed, this doesn't seem to have any connection to the Network Solutions problem. It looks like another DDoS attack that just happens to be taking place at the same time. There may be some devious connection between the two, but nobody seems to be making that case.
(And of course nothing is "originating from isprime" -- those source addresses are forged.)
Do not meddle in the affairs of troff, for it is subtle and quick to anger.
