Promissory estoppel only works against those who make promises to you.

What about people who were not born at the time you made this license 
grant to everyone?

quite reasonably argued that what you are doing is making an OFFER to 
everyone, which they accept by actually acquiring a copy of your 
software (or, more likely, by distributing it or modifying it).
