This is not true. Isn't it obvious that "basically because it wasn't Lisp" is shorthand for "because of a bunch of respects in which it differs from Lisp and Lisp is better"?
Note that the comment you're replying to links to RMS's more complete account of "why you should not use Tcl", which lists a number of respects in which he considers that Tcl is not suitable as an extension language. For instance: "It lacks arrays; it lacks structures from which you can make linked lists. It fakes having numbers, which works, but has to be slow." And: "Tcl has a peculiar syntax that appeals to hackers because of its simplicity. But Tcl syntax seems strange to most users." (Yes, it is kinda ironic that he said that and then proposed using Scheme. But, as he said at the time, the intention was to have two syntaxes with the same semantics, one of them Lispy and one more conventionally "algebraic".)
RMS also did not say that "Tcl was being developed by an Evil company", nor that that was a reason for discouraging its use. He said: He didn't like Tcl; Sun were trying to get Tcl made the de facto standard extension language; he wanted to make sure that didn't happen. There's no suggestion at all that he wanted to stop it happening because Sun were evil.
