This lacks a definition of “service”.
I also expect that there is a point where you have sufficiently
isolated yourself from the “service” (whatever that is). After this
point, there is no need anymore to provide source code for the
remaining parts of the system.
It would also greatly help to sketch a real-world deployment which you
think that this license allows, and a list of major system components
(load balancer, kernel, web server, application server, language
runtimes and compilers, other build tools) which would have to be
provided under this license.
I don't think a user can be compliant with this license on GNU/Linux
(because the user cannot distribute Linux, GCC, its run-time
libraries, and glibc under your new license—all are “use[d] to make
the Program”). Switching to FreeBSD will give users a non-copyleft
software stack which they can perhaps distribute under the new
license, but I still have doubts whether these users can actually meet
that requirement for other affected components, like Python.

Could you please discuss your objectives publicly? I assume that they
have something to do with increasing revenue, by stopping certain
existing practices without a separate, commercial license. I don't
think it is about getting more unpublished forks out in the open,
Is it your goal that GNU/Linux distributions stop shipping
pre-compiled binaries with (community) support?
Do you want to make it too risky for any business to run your software
without a commercial license?
Do you want to make it impossible for distributions to publish
container/VM images containing your software which can be readily run on
someone else's container/VM host?
Do you want to prevent container/VM hosters to offer ready-made images
that their customers can deploy, at their own cost, so that they can
use your software this way?
Do you want container/VM hosters to stop offering access to network
services which are a thin wrapper around your software?
My hunch is that you want to target the container/VM hosters for the
last scenario, but I think they will just switch to the second-to-last
option, without any net benefit to you or your user community.
On the other hand, you did not remove the cloud computing exception
from the GPL, which is why I'm so uncertain about your goals.
