What is the value of automation in general? Changing opex (training & paying a single human to post propaganda) with capex (buying another server to host a thousand bots posting propaganda, plus some fixed opex to pay a programmer to orchestrate it all). Servers are cheap, and some people with megalomaniacal dreams of influencing society through information have deep pockets. This quantitative change breeds qualitative change. Any time computers are used against us, be it in information warfare or physical, the reduced cost and decreased risk mean the activation energy is lower and the scale so much greater. The barrier to entry becomes lower, too.
