"Open as in beer," if I may.

I think they mean 'open' as in nobody is dining at that table and it's available, not a reference to software development processes.

Indeed. Just highlighting the correlation between possibly-nefarious software and non-libre software.

What does this mean?

I understood it this way:

OpenTable sounds like it would be open-source, but it appears that it isn't

I think the parent comment to yours made a sarcastic take using a variation of the popular ambiguity Free as in Beer [1] that usually differentiates between free as 0 cost and free as freedom as a reaction to the OpenTable software being free to use rather than open-source

Heh

Free as in beer

Well, do you want to drink an open can of beer?

You go into a bar, you order the IPA you liked someplace else, you see they've got a heap of cans... the bartender reaches under the bar and hands you... an open can.

No right? You don't want that one. Why the hell is it open?

Do you have a source on that?

Really what is happening here is that companies that advertise on Facebook push conversions to Facebook to “close the loop”.

Unless a company is advertising a service on Facebook, there is nothing to push to them for this purpose. Are there Yelp and OpenTable ads on Facebook targeting users booking reservations? Have you pulled your results and see those?
