At least here in the UK (which has the second most offshore wind generation in the world behind China) it's both - onshore wind got stuck in NIMBY planning hell and there's not really enough land in the right places to make it an easy option. Also, it looked for a while like with sufficient investment offshore wind could actually wind up being cheaper due to higher capacity factor, larger turbines, etc. Frustratingly, a lot of the British press has been pretending that the NIMBY issues didn't exist and the current government just made them up for ideological reasons or because their super-rich donors didn't like wind turbines, along with presenting onshore wind as the solution to all our problems and essentially ignoring the offshore wind and pretending the government has done nothing on renewables. (This seems to happen with literally everything - whatever the current governemnt didn't do or cancelled is spun as a magic solution and any problems it was having before are written out of existence.)
