Is that like "smokeless" not meaning "no smoke?" Years ago, some gunwriter used the pen name "Les Smoke" on his articles.
Well, a French 75 and every other tube artillery weapon will recoil substantially if the spade is not dug into the ground. It was, however, the first field gun with a recoil mechanism and that allowed the gun to do the recoiling while the carriage remained still but it still had to be dug in in order for that to happen. The advantage was mostly in laying the gun; it didn't have to be re-aimed between shots.
The French were in short supply of artillery at the beginning of the war and used some very old guns that had no recoil mechanism. They were used with ramps to make the guns return to battery. They caught up later in production and even supplied the US Army with most of their guns, which is why most US Artillery has the same nominal calibers as the French. The British supplied us with 8-inch howitizers, which is why we had, before decimilization, 8-inch howitizers when everything else was in millimeters. We also made our own 8-inch howitizers and 75mm guns.
