You are describing competition within a platform, which is happening in JS as well: EmberJS vs AngularJS vs KnockoutJS etc. Do you really think this kind of competition is bad?

I am talking about competition on a higher level: e.g. Ruby on Rails vs ASP.NET vs JSP. RoR was not the first one. Do you really think this kind of competition is bad? Was inventing Linux a bad thing because we already had other OS's?

"company going at it and inventing something new on their own" - the very definition of competition: generating something new to get a competitive advantage (new platform, new technology, new framework).
