It looks like the iPads were for the department, not the guy's personal use. It's a little bit dubious given that it's the same agency asking for and receiving the benefit, but money is fungible. Suppose the Sheriff had insisted on iPads for some other department, like the schools.

Governments do stuff like this all the time. In fact constituents get mad when they don't. The Planning Commission is considered derelict in its duty if it just gives away a building permit without getting something good from the developer in return (park, street cleaning program, extra BMR units, promise to use union labor).

SFMTA considers corporate philanthropy, coverage of unprofitable neighborhoods, and low-income discount programs when deciding who gets the permit to run scooters in San Francisco.

If it is bribery when a government agency asks a permit applicant to spend a bit on the agency's mission, then there's a lot more to prosecute all over the Bay Area.
