Game streaming services like that are harder to reliably hardware fingerprint and introduces unusual install patterns (same game potentially repeatedly installed large amount of times by same user).
For DRM and ban avoidance detection this means either false positives (which is bad rep) or if it's tuned to ignore those signals on specific service provider hardware makes it easier to do account sharing (and thus not buying the game).
I always assumed that the streaming services had negotiated to receive DRM-free versions specifically to avoid this issue, similar to the DRM/telemetry-free versions of Windows used on air-gapped government networks.
