This appears to be a pretty bad move from DataCamp. The original incident put DataCamp in pretty bad light at that time. I feel the reputation actually recovered pretty well since then.

I'm a premium member of DataCamp for 2-3 years and also an avid user of Rstudio and a fan of many of their staff.

I may be missing what the CEO is referring to but I haven't seen much disparagement of DataCamp by Rstudio.
