The origins of these clauses appeared to be entirely from third party lawyers, probably derived from some boilerplate contract. I presume their priority is to maximise legal "protection" for the company at all cost... even if it drives employees away, so it's not necessarily something the company explicitly asked for. Whether or not you are able to push back against them probably has more to do with the company culture and whether the leaders or hiring managers are sympathetic to developers and how the FOSS world really works.
I think this is probably true for most small companies, that it's incidental and intended for protection... but obviously in this case Bumble seem to actively be exploiting these clauses for gain rather than protection.
