Does it really need pointing out that a headline on huawai.com is a claim by Huawai?
For Cisco, their press releases seem to be here: https://newsroom.cisco.com/pressreleases
I haven't looked through all of them because I'm lazy, but scrolling through them I haven't yet found one that isn't in the 3rd person.
And if you go on Google and search some text from a press release, you'll find tons of articles using the headline and body completely verbatim like it's their own article. This is intentional.
Because that's how you do press releases.
News outlets print them verbatim, and it's traditional to read like that (as opposed to e.g. "we released a CPU" which on a news outlet it would make it seem like the outlet's team released the CPU").
