And oscilloscope manufacturers. You can typically "unlock" more bandwidth with a code after purchasing. The delivered device is capable of sampling at greater bandwidth but the software prevents it above the paid-for bandwidth. I think Keysight are probably the worst offenders but I think many of them do it now. FOSS firmware for modern scopes seems a pipe dream given many now use custom FPGAs.
