You were correct in saying "trolling" -- the post was spurious antagonization based on nothing. NO
Yes, it is certainly possible for lifetime SPG Platinum and Starpoints transfers to go away, but those risks were created during the VSE spinoff, not the Marriott acquisition. From a legal & contractual perspective, Marriott's acquisition changes absolutely nothing since they are buying Starwood in its entirety including the Westin & Sheraton brands, to which SVO/VSE/ILG has a long-term exclusive license which includes the ability to provide Elite status and points. NO
The only real risk in my mind is points devaluation, which is a problem for all SPG members not just SVO owners. However, notwithstanding Marriott's "responsibility to shareholders," if one of the stated reasons for acquiring Starwood was the value of the SPG program, then it doesn't make a whole lot of sense to simply transform it into Marriott Rewards and obliterate its inherent value. Will we see changes? Yes, almost certainly. But while I don't see Marriott's acquisition of Starwood as a "net positive," I also don't think reality is going to look anything like the pessimistic doom and gloom scenarios being discussed.
