Sure, in the case of private equity rollups in HVAC and electric and plumbing you often get higher rates but professionalized systems including real contracts, phone answering, emailed invoices, real quotes, real terms, enforceable warranties. Many who have trusted vendors may view this as degradation because of the cost increase but for others (a new homeowner with a job), the professionalization is a positive.

For software like Zendesk that was already thoroughly professionalized, I agree, it's hard to think of positive attributes to a PE buyout!
