Remember that this IS Musk; not very predictable. But I'm going to try... Since Musk has stated that this was NOT to make money, I imagine that triggering the poison pill, and THEN dumping the shares would tank the stock. Musk did say "final offer, and if rejected, re-evaluate". The poison pill trigger? Not something talked about.

I hold some shares of TWTR, and would continue. For the lulz.
