Its not to high or bad for them, it’s more like it just pushes the system to its max over and over. They are designed for fast charging.
Its like stretching a rubber band that can go to 3ft over and over. Its part of its design, but it will cause more wear and tear then just stretching it a few inches.
Is this because the power on fast charges is too high and bad for batteries in the long run?

Not "too high"technically. But does put more load on the battery, causing more dendritic growth in the cells.
