Quite so a moving observer sees higher velocities or lower velocities
from any source.

Our observations may be correct but our analysis may be flawed and our
conclusions wrong.

So we may observe nulls in the MMX and analyse it as showing light speed
I variance and conclude that SR is correct.

It takes the greatest genius Arindam to point out the analytical flaw
and the horrendously wrong conclusions.
