Facts as you define them would be impossible to confirm. You would need to trust the stated intentions of each app and framework found to be doing this. Nothing short of legal discovery will have a chance at defining facts about their intentions. We can only evaluate their response for maturity, competence, and authenticity, and combine that with past knowledge to try and evaluate whether their stated intentions are an accurate reflection of their true intentions. For example: "Did they honestly make this mistake or were they planning to use that innocuous framework call to implement clipboard-theft?" cannot be proven to be "honest" as a lack of evidence of dishonesty will be interpreted by doubters as "we haven't found the evidence of dishonesty yet". There are no facts that can usefully satisfy this question. It would speak highly of LinkedIn, though, if they were to announce that they've also evaluated their Android app (where this warning is absent) and identified and removed code there as well. But that, itself, is no proof of either honest or dishonest intentions, any more than any other facts will be.
