Apparently, for the first anniversary, Eisenhower suggested that “formal ceremonies would be avoided” since the war still continued in the Pacific. So maybe minimal celebrations in 1945 influenced what some people thought later.
Also, since D-Day anniversaries are a much bigger thing these days than before, maybe that also colors how people today interpret any alleged lack of enthusiasm of the early years.
But here are 3 cites from local museums and a committee that seem to show the local contemporary populations of the day were in favor of ceremonies, memorials, museums, etc.
According to the Musée du Débarquement, the first D-Day museum which opened in Arromanches on the tenth anniversary:
As early as 1945, local councils in the area of the Landings were meeting regularly to coordinate the necessary reconstruction: the Prefect of Normandy was presented with their proposals for urban and regional planning and development, signal monuments and commemorative plaques, and the organisation of anniversary ceremonies. The D-Day Commemoration Committee, founded in 1945, was tasked with the commemoration of 6 June 1945.
The D-Day Landings Committee (which I assume is the same thing as the D-Day Commemoration Committee and I also think is a civic French non-profit as opposed to a government committee), says:
…the Landing Committee brought together mayors and elected officials from the landing coasts of Calvados and the English Channel.
And The Airborne Museum at Sainte-Mère-Église, which recently partnered with Musée du Débarquement, states:
They both have been created thanks to the inhabitants and the local elected representatives’ will with the support of the D-Day Landings Committee…
So maybe we can’t rule out some local people avoided early celebrations or memorials, but there seems to have been a considerable amount of involvement from local officials, representatives and councils — all of which probably would not have been in favor of doing so if there was any kind of widespread public anti-D-Day sentiment — as well as the local citizens. That civic involvement seems to have been present continuously from 1945 through today.
