Because of 1995 (the decision was made to drop him then and Frentzen was spotted and contact was made fairly early) and because Williams have generally taken the stance of team before driver - they've always felt that designing the best cars would bring them the best drivers and never had time for keeping drivers simply because of past results.
That said, recently Frank has admitted dropping Damon was the biggest mistake he made (most probably because it had the consequence of Adrian Newey then leaving).
Damon Hill is one of the most under-rated drivers ever, it can never be said enough how well he did in his first full year against Prost and then again having to shoulder team leadership at such a low point the following year. Its weird and impressive to think that Hill was a similar age to Senna..but had well over half the experience, really hits it home how late Damon started his career.
Unfortunately, people seem to have got used to rookies being super-impressive straight away these days thanks to Hamilton and Vettel and so people seem to find it hard to understand or appreciate that simply being close to a WDC driver is impressive for a rookie.
He should have retired in 1998 though, 1999 was torture really for everyone involved.
