The only downside I've encountered to running GrapheneOS so far is that I can't switch to it out of spite to this latest attack against the mere idea that citizens deserve privacy.
GrapheneOS is currently under a state sponsored attack attempting to misrepresent it as being for criminals, which we covered a bit at https://grapheneos.social/@GrapheneOS/114784469162979608. These poorly researched, biased and inaccurate news stories have led to more harassment towards our community and team.
