There are a lot of different things you can say about Adele and Lana, but if you don't see why this is a relevant comparison then
What he's saying is basically that now she has better producers so her music sounds better? Uhm, duh. If she has the talent, why does it matter whether she was discovered by an agent or her daddy brought her the producers? 99,9% of talented artists are newer discovered and they could be making amazing material if they were able to buy the right producers.
He didn't say her music has changed. He called her early work bland and unoriginal and didn't offer much praise for anything she has released under her new name.
Of course her videos are still up, and "not bad" is an interesting way of putting it. It doesn't have to do with her bouncing around like a wild woman, it has to do with her actually being able to sing well. And he brought her father up because of the cosmetic changes that accompanied the change of her image. He's assuming there's support somewhere because she has no other notable career and has never released any commercially successful music prior to her re-invention.
I didn't bother to read the article, but who is he to judge what's bland and unoriginal?
He can vent all he wants, but his opinions are just his opinions. Oh and he doesn't have the evidence for any of that, he's just purposely jumping to a conclusion that would belittle Lana's reputation.
