Salesforce has "unlimited PTO", which is what it is. I'm not a fan of such a policy and depending on team, it is probably better than Amazon's 10 days of PTO.
Acquisitions (depending on how they are handle) go through a period of autonomy and then absorption. Saw this when I was with MSFT and Skype.
Honestly this post sounds a bit whiny and lacking reality in how acquisitions go about.
