Yep its not definitive. The only real data from that article was from cloudflare which showed some differing numbers. But thats all. I personally think we will know more once we have all the other trackers out there pull independent numbers.

Articles coming out seem to be what people "feel" like it is. Which isnt real data haha. All we can definitively say is that Linux usage is up from multiple trackers (stat counter/Cloudflare/Steam/etc...) but time will tell how much.
