What about free software that reimplements something you have worked on by day? Should be quite clearly the pro-employer interpretation and not free speech if the problem space is the employer's core business, but maybe debatable if it's just domain independent supporting infrastructure (someone already mentioned JS tables, surely not core business if your employer is e.g. a bank) I think that this must be a quite common situation: someone works on a solution to a "supporting" problem (js table or whatever), feels that the approach taken might be worthy of being a clean, reusable library. Maybe the thought of publishing isn't even there yet, it would just be nice to have the the API cleaned up for reuse as an in-house library. But there's no corporate time for that. Next stop: clean room supplementation from memory for open sourcing. Feels innocuous, but has trouble written all over it, good luck with "free speech". And it's tragic, because the employer would most likely be the sole beneficiary of the cleaned up reimplementation.
