Sicilian Defense Counter

I saw this move - 3.Bb5 from a chess website I subscribed to but don't want to pay to get the lesson, especially because I don't know if the move is good.  Can anyone help me analyze it?

"[1 e4 c5 2 Nf3 Nc6 3 Bb5] has become a popular way to avoid the main lines of the Sicilian and their heavy theoretical debates. … The plan is … surprisingly difficult to meet in praxis, and Black players … need to be well prepared and patient in order to face it with success. …" - GM Vassilios Kotronias (2015)

It works against 2...Nc6 and 2...d6.  You would need something different against 2...e6.

What would happen after 1 e4 c5 2 Nf3 e6 3 Bb5 ?

a6 and black gets free tempi off of the misplaced bishop.

"... [1.e4 c5 2.c3] cannot lead to an advantage, because it neglects development. …" - GM Vassilios Kotronias (2015)

the Alapin is very playable (except as the main weapon of a 2700+ GM)

I see no reason to doubt that 2 c3 is playable, but the 3 Bb5 thing seems to get more respect - not that that should necessarily make much difference to a below-1000 player.
