Ultimately, the information is somewhat more substantive than rumour or conjecture since the existence of those tools has been stated by FD themselves. You may also want to keep in mind that the EULA covers the legality of them gathering metrics about how players interact with the game and each other.
If Frontier's monitoring tools are telling them that only 2.8% of players board hop, they are likely being told that only .00000000001% of players combat log so it's not a worthwhile issue to address.
