Taylormade is owned by a PE firm and somehow plenty of people on this site are good with still purchasing TM clubs. I don't really think this is the end of the world and potentially could open the door to LAB entering into other categories outside of putters.
I would be willing to bet that the deal is structured such that Sam is staying around for the medium/long-term and likely has a significant amount of rollover equity going forward. This is almost certainly a play for the current owners to take some chips off the table and also get access to additional capital to continue to grow the company.
