Idiots doing hardware installation, with zero experience, using 3rd party cables incorrectly, posting to social media, and youtubers jumping on the trend for likes.
These are 99% user error issues drummed up by non-professionals (and, in some cases, people paid by 3rd party vendors to protect those vendors' reputation).
And the complaints about transient performances issues with drivers, drummed up into apocalyptics scenarios, again, by youtubers, who are putting this stuff under a microscope for views, are universal across every single hardware and software product. Everything.
Claiming "DLSS is snakeoil", and similar things are just an expression of the complete lack of understanding of the people involved in these pot-stirring contests. Like... the technique obviously couldn't magically multiply the ability of hardware to generate frames using the primary method. It is exactly as advertised. It uses machine learning to approximate it. And it's some fantastic technology, that is now ubiquitous across the industry. Support and quality will increase over time, just like every _quality_ hardware product does during its early lifespan.
It's all so stupid and rooted in greed by those seeking ad-money, and those lacking in basic sense or experience in what they're talking about and doing. Embarrassing for the author to so publicly admit to eating up social media whinging.
