I don’t know of a specific theme in the neubrutalism/neobrutalism style (names that are generally used to describe this style or aesthetic), but it shouldn’t be too hard to make.
For anyone unfamiliar it’s generally defined by flat, blocky layouts, with thick borders, single color drop shadows and a few bold high contrast colors (think CGA and EGA monitors if you’re that old). It often features “unpolished” elements like flat simple shapes. Bold fonts and monospace fonts are pretty common.
There are a few resources out there if anyone wants to play around with this style.

You can confidently say that this is fine for most consumers today. There really isn’t a great argument that this will serve most consumers well for the next 3 to 5 years.
It’s ok if well informed consumers are fine with a compromise for their use case.
Misrepresenting the product category, and misleading less informed consumers to believe that it’s not a second rate product in the current generation is deeply anti-consumer.
