MIT requires that you fulfil: "The above copyright notice and this
permission notice shall be included in all copies or substantial
portions of the Software." (https://opensource.org/licenses/MIT)

Whereas GPL 2 merely requires that you "[...] conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty [...]".

Thus, arguably, GPL 2 is more permissive.

Well, luckily the FSF does not think that the MIT license is
incompatible with the GPL license, though it finds the term "MIT
license" misleading and discourages its use, see
https://www.gnu.org/licenses/license-list.html
