Yes, I think this is a typical brand lifecycle. Somewhat niche brand gets famous due to high quality and appealing image. Brand gets bought by big group, with a lot of expertise in distribution and marketing. Quality goes downhill, prices skyrocket. Brand eventually loses appeal.
The LVMH Group does this all the time. But arguably, they don't lower quality too much.
When the standard price for a tshirt is something like $50, they don't need to worry about manufacturing price or cheaper competition. That's a different business entirely than primark selling $1 or $2 tshirts.
But they evidently did maximize short term profit by selling the company.
For instance Whataburger uses fresh eggs and scrambles them on site. That’ll go by the wayside in favor of McDonald’s-style pre-made and pre-packaged eggs generating waste and lowering quality. But it’ll make the food easier to replicate nation wide creating shot term profits from growth until consumers have the predictable “I don’t see what all the hype is about” reaction, damaging or possibly destroying the brand.
