No it isn't. You can run it through plagiarism software which is specifically designed to take into account scenarios like your suggest and it'll be flagged.

For example why do they all use the word "provide" there are hundreds of synonyms that work just as well ("given", "enabled", "allowed", "have", etc.). They weren't accused of "providing" the access, it's a word they've chosen to use.

The specific accusation was about the NSA, why are the denials using "government agencies" or synonyms rather than NSA. There might be perfectly valid reasons, but the chance that they'd all make the same decision to use it independently ?

Why are they all in current tense rather than "we have never x" ?

If there were on or two similarities it might be coincidence, but we're talking about dozens of grammatically and phrasing choices.

Because it is plagiarism. Do you honestly believe the PR people who wrote this didn't also read what others wrote? I don't think they released their statements all the same second.
