In all seriousness, any time a minor league signing like Vogelbach sees the team sign a future hall of famer to the same position you can't help but think his days are limited.
Votto's rolled ankle is worse than we thought (still isn't playing) and had to have helped Vogelbach.
But Vogelbach does project well and the team must seem hellbent on having a lefty bat with some thump on the bench. With versatile utility players up and down the roster it makes sense.
Also, it seems like this org places a high priority on being a player friendly org. I'm sure when Vogelbach signed, certain promises and guarantees were made to him regarding giving him a fair shot to make the team and things like that. Pulling the rug out from underneath him in the last minute would cut against that.
