The problem with the Brompton is the what the company is managed: its not managed like a bicycle company but like a fashion company with the unique aim of maximizing profit and the bike itself is considered by the management like a fashion object more than a bicycle with as consequence that the management is not looking at technically improving the bicycle but making special series, promoting the British origin of the bicycle, creating an artificial penury of bikes and very long delivery time...

This strategy worked for a very long time but things changed recently, especially in Asia where the customers were tired to wait for a Brompton and bought clones instead.

While doing so, they discovered that several of these clones are as good as the original and not the crappy, badly manufactured, falling apart, dangerous bikes shown by Butler Adams in a ridiculous video he published several years ago.

And nowadays, the clones sell very well in Asia reducing the market share of Brompton.

Brompton then developed the T-line to try to recover this market.

But after so many years of not developing any new bicycle and not following the technical evolution of the bicycle industry, the company doesn't know how to make a good 2023 bicycle and is continuing to make stupid technical choices like the development of the miserable proprietary 4s derailleur system, continuing to use narrow high pressure tires, continuing to use a proprietary OLD on its rear wheel, choosing an inadequate proprietary mounting for the chainring...

Anybody who likes the Brompton understand why Andrew Ritchie left the company he created!
