Speaking from years of .NET work in state and federal government, the sort of dev groups that lean on Telerik or DevExpress have less leverage to build new things for themselves than you would expect, so the use of AI inside of them is predominantly for maintaining existing software. Decisions on how things get built at most public agencies still revolve around MS Access and WebForms due to a whole bunch of BS ordinances that legislators put in place; for those sorts of places a reliable vendor can absorb the blame if concerns surrounding accessibility, compliance, or security of your ancient web services crop up, while Claude and Codex put the liability back on your org.
