That's quoted out of context - you left off the next sentence:
"Obviously we’d prefer that you use us, but the main thing is to make sure that you get them in a place where the data belongs to you and not someone who wants to keep it under lockdown."
Sure there's a marketing message there but it's buried at the bottom of a long quite involved post, and fully disclosed. Hardly discredits the article just because he's an interested party, IMO.
The post was hardly worth writing in the first place. This is extremely standard social network (or internet company) practice. The privacy concerns of just giving a massive dump of all that data are very complex.
Given that, it's incredibly obvious the post was written as a self plug, and burying it was disingenuous. If that author had begun with, "this is an issue and we have a solution for you", it would have been much more honest.
