Just to kick off some discussion. Do you guys think that the shift from on-prem to SaaS is indicative of a move towards rent extraction?
Only when vendor lock-in and inaccessible data silos comes into play. And that's not a problem specific to SAAS.
Good luck getting 1-10 Gpbs data transfer from most public SaaS to your own datacenter without having to pay over and above your current fee for Internet access (eg: have a look at what it costs to get just a TB data out of S3 -- on any budget (or prime) dedicated provider, 10-50 TB of data would be included - per month.
