TBF money means nothing to the Padres at this stage of their development, and they'd rather lose 90-100 games than win 80. None of the moves you mentioned has made much difference to their long term plan of being competitive in 3 or 4 years after which Hosmer's contract goes down to an affordable $13m a year.
Every move they make is either to acquire young assets, acquire assets that can be flipped / rebuild value then traded, or in the case of Hosmer for "veteran clubhouse leadership". They love Hosmer for helping the younger players, whether that's worth his contract (it obviously isn't!) isn't really relevant right now when they wouldn't be spending money on anything else.
It does look bad though - at some point moves they make have to produce something otherwise they'll be stuck in rebuilding for too long and the front office are going to lose their jobs in a few years.
