Shackling accountability is no way to run a team.

That being said, there's value in ICs contributing to a roadmap, if they're trusted. Being a 'leaf node' and closer to customers can make people more in touch with problems and solutions a business could implement (at least, that's the theory). But in most organisations the customer and business problems are well-removed from engineers / designers leading to lower quality insights from those people; but in either scenario it always seems like management is out-of-touch.

I as an IC would personally be fine having a bit of 'skin in the game' if the risk:reward ratio was more favourable, but that does seem rare at modern corporates.
