If I were a team owner would I have either of them? Maldonado only got the seat by paying his way in and his comments about Williams show what type of person he is.
I don't think Williams has too much to complain about, effectively PDVSA will be bankrolling two teams this coming season, I'm sure Frank settled on a rather large wedge as compensation for them cancelling their 3 year contract.
When anyone is departing from a team it can always feel like the normal ups and downs have more meaning or cause, really depends how sour the relationship becomes. I seem to recall one Fernando Alonso sticking the knife in over Stepneygate, to assist the FIA and Ferrari, against McLaren - for whom he was driving at the time, but had fallen out of love with.
