Of no, it isn't, and your presumption is an extremely unfair one. I strongly suggest you change your attitude to allowing some tolerance for other people's views.
Alerts in England used to be by knocking the table. Mrs Chadwick, who was still playing tournament bridge at 101, always asked for no alerts because the actual knocking upset her physically.
I have played against people who never ever under any circumstances ask what I am playing. Some of them would prefer no alerts because they find them distracting and they are clearly of no help whatever.
Lesser players, as mentioned by another poster, sometimes find alerts intimidating, and some would much prefer no alerts.
So there are three sets of people, some of whom would prefer their opponents not to alert, and are making no accusation whatever about their opponents' ethics.
I am also somewhat worried about the word cheating.
Of course, there is no doubt some people who would ask their opponents not to alert do so because they feel their opponents might use the information from the alerts illegally - and in some cases there is no doubt they would be correct. But it is only cheating if they do so deliberately and knowledgeably - and there are a lot of people who use UI but not deliberately and not knowledgeably.
So even if a player wants his opponents not to alert because he does not trust their ethics, that is not necessarily a tacit accusation of cheating. It may be an accusation of bad ethics, certainly, but rarely would it go further and presume they might actually cheat.
