I worked for an agency helping close a midwestern diocese. They branded it a positive thing but I was in the meetings with priests hearing the low down and how closings will go. It’s sad. Half the priests are old and just trying to get through. The other half want to help but are being told the cost of their renovations is more important. Let it crumble.

The answer is yes! It depends on the type of material and the goals. For instance, the iPhone 4 was supposed to have a white version on release but it was delayed. Apple eventually blamed the different in heat and UV radiation being different, if I remember correctly. Vague rumors that it messed with the proximity sensor also floated around. This was during the antenna-gate “you’re holding it wrong” era. Could be all BS and there was no formal explanation given.

Most times it probably doesn’t affect very much but manufacturing engineers spend a lot of R&D to make sure it doesn’t by the time things to get to consumers!
