"HP and Oracle don’t exactly represent the heart of Silicon Valley today and what makes it special/unique. I actually think zombie corporations like Oracle,"

This sentiment is problematic. Oracle has 130 000 employees and $40B in revenue. That's massive.

They are a tech company, not a media company like FB.

They are a lynchpin, just because 'we don't like them' doesn't make them 'not' that.

It's like Burning Man: everyone has their view on 'what it is' but really they mean to say 'what it ought to be'. What it is ... is more objective.

Oracle and companies like them are a huge part of what the SV is, full stop.

It's 'mostly' bad for SV to be losing Oracle.

The 'Bay Exit' story is probably overblown, but it's also very real, and less to do with 'leavers' than the fact it's just easier to do things elsewhere in the first place, at least for some kind of companies.
