"the inner of the two, takes little more than 10 days to complete an orbit around the star, while GJ 1002c needs a little over 21 days."

This means the orbiting planets are probably tidally locked to the star, which means one side is always facing the star and the other side is facing away. It's unlikely these are "habitable" or "Earth-like" planets.

But the hype should keep the funding going.

Yep, I was curious so I did some math, with the single assumption that the planet radii were the same as Earth’s.

The inner planet should have tidal forces ~400 times those of Earth at the spring tides (both sun and moon forces added together). The outer planet should have tidal forces ~90 times Earth’s, compared similarly.

Mercury is tidally locked, and its tidal forces are only around 2.5 times Earth’s.
