Recuerda que los diccionarios pasan por referencia. Tienes que crear uno nuevo para no modificar el original.
| all_Platzi_workers = list(filter(lambda x: x['organization']=='Platzi',DATA))# Using filter, generate a list with all the Platzi workers | ||
| adults = list(filter(lambda x: x['age']>18,DATA))# Using filter, generate a list with all people over 18 years old | ||
| workers = list(map(homeless, DATA)) # Using map, generate a new list of people with a key 'homeless' with True or False values, if 'organization' have something or not | ||
| old_people = list(map(older_than_30, DATA)) # Using map, generate a new list of people with a key 'old' with True or False values, if 'age' is greater than 30 or not |

Vas a notar que al imprimir old_people tienes también la información de homeless, por que se modificó DATA en la línea anterior.
