He does "disclose" in related blog post [1]: "I don’t work for Neo4j anymore, why am I here defending them? Well… that and the fact that I still have a dinghy load of vested shares I have to sell so I can buy a place in the Villages and begin a new life as a golf cart driving day drinker."
This seems like a series of post on benchmarking results from different vendors so if he "disclosed" it once I don't think that there is need for another one.
Author here: I did not write that I was proud of not knowing Python. I just wrote that I don't know Python. The thought of trying to understand 2k lines of it looking to see where Memgraph 'cheated' to make their product look good and the other bad was beyond my current capabilities.
So what you're saying is that he is opinionated about popular languages just like every other developer in the world. You don't think you can trust him to write databases because he doesn't like a language that he would never use to write a database.
Weird. Linus Torvalds also hates one of the most popular languages in the world: C++. He must not know anything about operating systems...
The author is discussing facts and providing replicable results. Disclosing their "conflict of interest" more clearly would be laudable, but even if they lied to us and pretended to be an independent journalist, that might sway our opinion of their character, but it would have no effect on the veracity of their writing.
What they say can be classified in three categories: Objectively right, objectively wrong, or subjective claims. Their conflict of interest only affects our evaluation of subjective claims.
Things that can be assessed as right are right even if they were said by Vladimir Putin; things that can be assessed as wrong are wrong even if they were said by Florence Nightingale. It is an ad hominem appeal to motive to suggest otherwise.
The author disclosed it in the first line of the article, albeit in a joke about death row records. Looks like someone needs to brush up on their west coast rap discography.
