We have no clue what Machado wants or planned to do.
I don't think two months in Philly would have had a real impact on his decision, in fact, if the Dodgers don't want him, he's more likely to sign with Philly because he's seen how Utley has been treated (and he can talk to Utley about Philly)..
Nor will money be the deciding factor, once money hits a certain level, other than ego gratification, it has little value to the player (how many cars can you drive, how big of a home do you need). And enough teams will be bidding that money will hit that level.
It'll come down to a mix of motives, family, lifestyle, media, etc.
