Copyleft (GPL, AGPL, MPL): derivative work must stay open. AGPL also covers software offered over a network, which blocks most closed SaaS wrappers.
This matters most when you plan to sell a hosted version. A permissive licence means anyone — including a competitor with more capital — can do the same, so your defensibility has to come from distribution, support or data, not from the code.
Sync-in is shipping code consistently, so a buyer comparing your product will find a maintained free option. Price and position against the total cost of self-hosting it, not against the paid incumbent's list price.
Winnable, but differentiation is not optional. Pick one underserved segment and be visibly better for it rather than competing feature-for-feature with a free tool.
