Not op, but in my bubble:
- DRM.
- Owner-unfriendly device locks (such as manufacturer-controlled secure boot or locked-down OSes).
- Inability to audit network traffic from one's own devices, i.e. an IoT device.
- Remote attestation, when in opposition to open computing.
I could also see folks seeing the use of cryptography as "having something to hide" - I don't personally agree.
