Erm...
Could it also be due to the fact Cisco kit isn't as far ahead as it once was as well as "Trumpian chaos" etc.
There are equally decent but significantly cheaper options out there now. Especially where switches and wifi are concerned. TP-Link for example makes some reasonably good astonishingly cheap switches and Ubiqiti makes some rather solid WAPs.
I find it hard to recommend Cisco these days mainly due to cost but also due to configuration and management requirements. I don't seem to have the luxury of spending half a day setting up a switch these days mainly because of budget changes etc try and convince a business that you need to bill 3 hours to set up a switch, they will cry with laughter.
Its also pretty difficult to sell a £1000 Cisco switch vs a £150 TP-Link switch.
I accept that there may be some specific use cases for Cisco kit but for the overwhelming majority the cheaper option will suffice.
