paid by Ubiquiti: "WiFi Access Point Testing in a High Density Environment" - Do you trust them?

[Krisbi]

So an unknown indian company tests a couple of access points (https://alethea.in/wifi-access-point-testing-alethea-wifi-experience-test-lab/):

Aruba AP325
Cisco 3802i
Meraki MR52
Mist AP41
Ruckus R720
Ubiquiti UAP-AC-SHD

The tests were paid by Ubiquiti and of course Ubiquiti wins. How did they influence the result at all? I don´t believe that the Cisco or the Ruckus have less performance than the Ubiquiti device...
