Else, as first poster said, the process is tyrannical.
Not every business decision requires every single persons input either, and although you may be affected that doesn't mean your input was as valuable as everyone elses. The CI team's choices might affect my branching structure. Tough, that is their responsibility. If it's extremely detrimental then you can raise concerns, talk to people, get out of your seat and work with the humans around you.
We don't need another revolutionary management fad, where a hundred employees sit around a satiricaly large table and vote by show of hands. That works amazingly at small companies and it's why I prefer to work at them. But let's get real, management at scale is hard.
Ultimately though, if you feel like you don't have a voice where you are, work to get a voice, or find a company with a structure that works for you.
Everyone should have a voice but not everyone needs to literally be at the table. Seeing companies go from small to larger and seeing how the flat structure begins to show caveats as a team grows, I agree everyone should have a voice, but ultimately a decision needs to be made and a big group of people are never going to agree on everything. You can bikeshed all day on which CI platform to use for example but ultimately a decision gets made by someone that there has been enough discussion and this is the platform to use.
That process can be horribly perverted and have the wrong people making terrible decisions but that is a separate problem, not a problem with the idea of consolidating many voices into a decision.
