You make it sound like Tesla voluntarily made the decision to share. They probably thought they had a moat.

[silisili]

The decision was completely voluntary, not following your logic.

If your argument is that they were afraid of a competitor, that may be valid, but doesn't make their actions any less voluntary.

It was not entirely voluntary, that's the point. The US government pushed very hard for an interoperable standard, and conditioned a big pile of IRA funding on supporting a fully-open standard. That was the carrot. The rest of the industry (manufacturers and chargers) also standardized and started building cars and charging infrastructure with CCS connectors. The farther this process went, the less likely it would have been that Tesla would have been able to force a switch, and so they would have had to (expensively) update their new and older cars to this standard. This was the stick.

But yes, it was all done through encouragement and coordinated coercion. Nobody showed up at Tesla's HQ with guns and forced this to happen.

More like voluntarily pushed or strong-armed by the prospect of governments mandating Tesla support a different connector thus forcing more complexity in their cars and chargers.
