I think it is actually 5m. 1m gets pretty close to spy satellite territory. The planet labs lens only has a focal length of <30cm.

Yeah 3-5 meters apparently.

And i would assume spy satellites can do much better than 1m.

According to wikipedia spy satellites has a estimated resolution of about 10 cm.

Modern Spy Satellites certainly do. However, there are rules that govern what a non-governmental entity can put into space.
