Must be true, its on the internet

If it was false there would be contradictory articles.

Its not false, but it is poor practice.

Using a pre-heated oven is also likely to exceed the component
temperature maximum slew rates. Most components will not only have a
maximum temperature, but also a max temperature rate of change specified
(e.g. 4 deg C per sec). This applies bit on heating and cooling.
Exceeding that can stress them and lead to premature failures. That's
without the problems of exceeding the maximum temperature limits for the
larger discrete components.

It's probably the best that can be done with domestic appliances though.
