Clearly any free software event is going to clash with _something_.
It's unfortunate that SFD it clashes with TLAP day in my opinion.
There is a completely inappropriate connection between real-world
pirates (currently Somalian coast etc) and their copyright-breaching
namesakes. I don't see that a Free software event would want to be
remotely connected with either of those no-go areas.

I disagree. I do not mind being associated with either kind of pirate;
