How is it disingenuous at all? It clearly specifies the conditions and re-emphasizes in the conclusion that the analysis was done based on which browser handles having a large number of tabs open better.
Also, the plural of anecdote is not data, but I routinely have more than 100 tabs open. So this analysis is clearly relevant and interesting to me.
Edit: proof-reading.
I guess we all have different definitions of "many" in the statement of "many tabs." I didn't think 100 open tabs is realistic, but enough people here seem to do it.
