I think it's really cool what they implemented. At least in v1 it was a sort of inverted ORM; it gets pushed object updates and does relation fixup(an Entity Framework term at least) as they arrive. It even looked like they created a decorator based lib with a syntax very close to ORMs so they could define relationships on the FE objects. Also, a huge fan of MobX.<p>But, man it looks like it has gotten really complicated and.. Well I guess this is the sort of thing you get to do as a technical co-founder of a company with traction. That is to say, Linear was just OK to me and none of these sync features seemed to raise it above any other issue tracker I've used. With the added downside that loading the workspace from the pub via the webapp could be excruciatingly slow.
