Einstein didn’t say that religion was needed for science. Cosmic religion is not a good term because any reader will associate it with our umbrella term religion while he defined something else. Writing it without context is manipulating any reader who does not have/take the time to read up on the term.
He firmly stated that he does not belief in any religion associated with any god or gods like all the religions OP probably means. Even going so far as calling such beliefs expression and product of human weaknesses.
He also wrote “the Bible a collection of honorable, but still primitive legends which are nevertheless pretty childish.” And “I, like yourself, I am predominantly critical concerning the activities, and especially the political activities, through history of the official clergy.” So he does se a conflict between religion like OP means and science. He only once made a statement in support of the traditional religions when he said he was positively surprised that the christian church opposed the Nazi regime. He later backtracked on this because the church supported the Nazis partially during the further years of the war.
He still stated he is no Atheist because he believes in the existence and governance of the fundamental laws of nature and what he sometimes called religion he defined as the aspiration to pursue the research on these fundamental laws.
Well there is the Stop Killing Games initiative started by Ross Scott and supported by the Pirate Parties. If they succeed, companies selling games in recent years will be required to either keep supporting their game or to make it available in a way so that others can ensure its continued support.
When this is achieved the step to free older games is small.
