How much difference was made by the Chinese competitors being able to use whatever IP they wanted, and Roomba being constrained by law and licensing, and not being able to enforce their own IP? What were the consequences of having to engage with China for manufacturing, effectively giving them the capability to clone any R&D on the fly, without having to figure things out themselves?

How much did regulation and taxation and red tape play into Roomba's inability to compete?

What sort of VC deals were they shackled by, in order to siphon off the data and abuse it for third party marketing, and other forms of enshittification?

There's a lot that American companies have been held back by. Some of it is actually good, consumer protective and well crafted, but it won't work if you allow other players in the same market to ignore the regulations and restrictions without consequences. Other policy is just stupid and self destructive, and other policies border on malignant, deliberately giving foreign companies significant advantages, directly and indirectly, without any other purpose.

American companies are way too easily forced into a race to the bottom dynamic, resulting in failure and huge wastes of money and effort.
