No. Pruning is done continuously. If you set it to 2 GB, then only 2 GB of blocks will ever be saved. Then, old blocks will be removed, to make a room for new ones. Only in today's version. And even today, many people don't do that. Also, many users use utreexo, or other kinds of nodes, where it is not required. Not to mention that you need to do it only once. Later, you can trust your own node, because if you cannot, then your whole setup is unsafe. And even if you assume, that you have to download it, then still: it is not something, which is easily accessible by the outside world, because when your node is in Initial Choang Vip Download mode, then it doesn't share blocks outside. It starts doing so, after downloading everything. And if pruning is enabled, then guess what: it will share only the last 288 blocks, or something like that, to the outside world. Which means, that if some spam has for example 2000 confirmations, and was done two weeks ago, then it will never be shared by pruned node to the outside world. Because even if you set your pruning to 200 GB, then still, only 288 blocks will be shared to the outside world, for privacy reasons.
