Obviously what you need to say but the reality is that you’re not in control anymore. That’s what an acquisition is.
If Cursor wants to re-allocate resources or merge Graphite into to editor or stagnate development and use it as a marketing/lead gen channel, it will for the business.
Anything said at time of acquisition isn’t trustworthy. Not because people are lying at the time (I don’t think you are!) but because these deals give up leverage and control explicitly. If they only wanted tighter integration, they could fund that via equity investment or staffing engineers (+/- paying Graphite to do the same.) Companies acquire for a reason and it isn’t to let the team + product stay independent
