How come? If you switch open source to proprietary software (as much source-available as it may be), there's a significant impact: a % of users won't use proprietary software; those who may will not find this software packaged on package managers; derivatives and companion projects may stop being developed. Where's the "no impact"?
If you'd install ES via deb or rpm or whatever packages from your Distro, this will affect you, as they will be sooner than later removed.
If there's a policy for open source-only usage, you will definitely be affected.
If there will be a diminished number of contributors (which won't like to contribute if it is not open source) and ecosystem (that will stop developing/growing being a proprietary project), you will be affected too.
