"Not having any evidence to corroborate" is logical reason enough not to make a claim.

But that is a different route. Claim that they don't have evidence. Or refute that the relationship is truly bad. This line was specifically "You can't make the claim that Samsung is then being screwed over by Google." Sure you can. Just provide evidence.

So, change that refutation to "what is your evidence taht they are getting screwed over by Google?" On that, you have my complete agreement.
