I'm thinking more of the design language and lack of modular functionality part here. Ikea stuff is perfectly fine and minimalist, but the FORSBOGG shelf and the GLOMBOR lamp never seem to be built with any kind of underlying design language in mind and may or may not go together. The BLOKKE box sticks out when you put it in the FORSBOGG. Yes there are notable exceptions (KALLAX inserts, etc.)

This is the same problem I see with these Stripe tools. This may not actually be a problem for real users at Stripe.
